Has there ever been a time travel movie that kept the logic straight?

Time travel is not logical, therefore there is no logic to incorporate. I saw looper last night and thoroughly enjoyed it. :thumbup:
 
If we can time travel to the past, then the past we change and affect will be a different alternate universe by itself altogether with its own future.

I speculate that no time traveler travelling backwards in time can ever return back to the exact same future he left from. I also believe that the past can be as fluidic as the future.
 
Looper got time travel wrong.

If
you went to the past and killed the younger you, the older you who did it would continue to exist.
The moment you appeared you created a divergent timeline, which is not the one you originated from. They portrayed it all as a "loop" and I don't agree with that notion.

That fails on the same basis as looper.

Disagree. For time travel to work, all paradoxes must be avoided. Therefore circumstances would always prevent the traveler from changing what already happened up to his/her current existence. Although the traveler could make changes to his/her past timeline, those changes always existed leading up to his/her interaction with his/her past.

I loved the book. The movie was forgettable. I don't remember a thing from the movie.

They got some guy who worked on The Fast and the Furious to try and jazz it up for a younger audience and I think that's why the movie was a miserable failure.

I remember that they didn't want the star to seem like the nerdy type so he rode his motorcycle over the archeological dig and only tagged along for a chick.

Oh I saw that movie. I thought it was really cool with the wormhole/teleportation but then lost interest once I realized the remainder and majority of the movie was them stuck in medieval times. Nothing makes a time travel movie more boring than when there is hardly any time travel in it and they're just stuck in the past. :/

The book was FAR from boring.

This is still a paradox since it creates recursive time. The past relies on the future, which relies on the past.

To which logic do you refer? Keep in mind, you're asking about movies that pertain to subject that aren't real...so any "logic" would have to be invented.
 
When it comes to past time travel and paradoxes...

Is much like an equation in which 2 or more variables are unknown and not enough information is possible to solve for both. Also, assume paradox's had the outcome of Doctor who, in that if you went back intime and caused something to change, thus changing you ever going into the past. The timeline resets itself to right before you travel to the past not knowing anybetter.

Now, assume like said engineering math equation to solve for both variables you must iterate, using a educated guess for X to find Y, which you plug back into Y to find X, which you plug back into X to find Y, thus iterating the values of X and Y until they converge onto true values of the equation (normally used in pressure and temperature curves in vapor and bubbles).

Now let us assume time travel is the same way. Everytime you go into the past you cause a paradox, it resets back to right before you go back into the past. Thus Eventually you will do something the way it was intended to cause the future you live in to be that future that you didn't know was caused by you before, or iterate another time until a paradox no longer exists. (basically going in circles until the one time it doesn't cause a paradox)

Thus if the universe was to act in such a manner, past time travel could be done without paradoxes happening and without the need of a alternate univers loophole (if we could ever actually time travel).

The alternate universe theory is used to break any possible paradox that could occur. Because once you go into the past, you are now a seperate being of your past self, and thus it willnot effect your future self since you are theoretically in another universe in which all is the same except the past you didn't learn to time travel.

isn't the logic faulty by nature?

I thought Hawking more or less dismissed the possibility of time travel simply because the grandfather paradox makes it more or less impossible. Or something like that.

I was hammered when I saw Primer, many years ago. Should probably check it out again.

Look, maybe I didn't say every single little tiny syllable, no. But basically I said them, yeah.

The perfect respect for the paradox.
